Hobbs Heirloom Premium 100% Natural Cotton with Scrim Batting is designed for quilters who enjoy using natural cotton batting and who are seeking extra strength in that batting. Strong, but also soft (and softer after each washing), Hobbs Heirloom Premium 100 Natural Cotton with Scrim Batting is perfect for quilts where a low loft is desired. This soft and pliable batting is made with very clean, high-grade, unbleached, long-staple, virgin cotton (which proudly displays the Cotton Incorporated Seal) combined with a very thin, polyester scrim (stabilizer) which is needle-punched into the cotton fibers. This scrim provides superior strength to the cotton, and prevents the cotton batting from stretching and distorting as it’s manipulated. Hobbs Heirloom Cotton Batting w/Scrim should be paired with medium or dark fabrics if paired with with white or light-colored fabrics, natural (unbleached) cotton can slightly darken the fabrics. Quilting/stitching may be up to 8 inches apart with this batting, providing quilters with many more design options! And yes, it’s also machine washable – shrinkage of 3-5 is expected.
